It is the prologue to the only fight that matters at Light Heavyweight?

That will be the question on many a mind this weekend. Adonis Stevenson will attempt his fifth defense of historyís 175 lb. crown but heís not just fighting the man in the ring. Heís fighting the perception that heís avoiding the most dangerous challenger to his throne.

Sakio Bika is the challenger on Saturday. Sergey Kovalevís is the shadow over this afternoon network TV showdown.
